Abstract

Keksintö tarjoaa käyttöön laitteen (1), jolla ilma poistetaan syöttönesteestä (3), joka käsittää nestesuspension tai lietteen, ja joka laite käsittää syöttö väylän (2), joka kuljettaa syöttönesteen (3) erottimeen (4), ja erotin (4) käsittää mekaanisen sekoittimen (5), joka aiheuttaa syöttönesteeseen pyörrevirtauksen erotuskammiossa (6) siten, että pyörrevirtaus synnyttää keskipakoispyörteen (15), joka erottaa syöttönesteen ensimmäiseksi komponentiksi (7), joka koostuu olennaisesti vaahdosta tai kaasusta, ja toiseksi komponentiksi (8), joka olennaisesti koostuu ilmatusta nesteestä tai lietteestä, ja erotin (4) käsittää edelleen laitteen (17), joka ohjaa pyörteen (15) paikkaa erotuskammiossa (6). Keksintö tarjoaa käyttöön myös menetelmän sellaisen syöttönesteen (3) ilmaamiseksi, joka käsittää nestesuspension tai lietteen. (Kuvio 1)The invention provides a device (1) for removing air from a feed liquid (3) comprising a liquid suspension or slurry, the device comprising a feed channel (2) which conveys the feed liquid (3) to a separator (4), the separator (4) comprising a mechanical mixer (5) which causes a vortex flow in the feed liquid in a separation chamber (6) such that the vortex flow creates a centrifugal vortex (15) which separates the feed liquid into a first component (7) consisting essentially of foam or gas and a second component (8) consisting essentially of aerated liquid or slurry, the separator (4) further comprising a device (17) which controls the position of the vortex (15) in the separation chamber (6). The invention also provides a method for aerating a feed liquid (3) comprising a liquid suspension or slurry. (Figure 1)
